[0080] The working principle of this utility model:

[0081] I. Working principle of Smart Coaster 1:

[0082] (1) Water level detection: When the user places the water cup on the sensing coaster 12 of the smart coaster 1, the gravity sensor 122 inside the sensing coaster 12 starts to work. The gravity sensor 122 indirectly determines the amount of water in the water cup by detecting changes in the weight of the water cup. During this process, the contact rod 1221 of the gravity sensor 122 contacts the bottom of the water cup. As the amount of water increases or decreases, the pressure exerted by the water cup on the contact rod 1221 will also change accordingly, and then be converted into an electrical signal output.

[0083] (2) Signal processing: The water volume signal detected by the induction coaster 12 is transmitted to the drive device 13 inside the smart coaster 1. After receiving the signal, the drive device 13 processes it, including signal amplification, filtering and analog-to-digital conversion, so as to convert the analog water volume signal into a digital signal for subsequent transmission and processing.

[0084] (3) Signal transmission: The processed water volume signal is sent to the external controller 3 through the first wireless receiver-transmitter 14. The first wireless receiver-transmitter 14 uses wireless communication technology (such as Bluetooth, Wi-Fi, etc.) to realize data transmission between the smart coaster 1 and the external controller 3. In this process, the first wireless receiver-transmitter 14 is responsible for receiving the signal sent by the drive device 13 and wirelessly transmitting it to the external controller 3.

[0085] (4) Power Management: The power supply device 15 of the smart coaster 1 provides power support for the entire system. The power supply device 15 includes a lithium battery 151 and a charging port 152. The lithium battery 151 is responsible for storing electrical energy, while the charging port 152 is used to connect to the charger 2 for charging. When the lithium battery 151 is low on power, the user can charge the smart coaster 1 by connecting the charger 2 to ensure the continuous operation of the system.

[0086] (4) User interaction: The smart coaster 1 is also equipped with user interaction components such as indicator light 16, call button 17 and control switch 18. Indicator light 16 is used to display the charging status and working status of smart coaster 1; call button 17 allows users to send operation signals by pressing, which are received by the first wireless receiver transmitter 14 and sent to the external controller 3 for processing; control switch 18 is used to control the opening and closing of smart coaster 1 to save power.

[0087] II. Working principle of charger 2:

[0088] (1) Charging function: The charger 2 is equipped with a charging plug and a clamping device 21. When the smart coaster 1 needs to be charged, the user only needs to insert it into the charging slot 23 of the charger 2, and the charging plug will connect with the charging port 152 of the smart coaster 1 to start charging the smart coaster 1.

[0089] (2) Stable clamping: To ensure stability during charging, the charger 2 is also equipped with a clamping device 21. The clamping device 21 consists of a fixed frame 211 and a spring piece 212. The fixed frame 211 is a cylindrical structure with an open top and a charging slot 23 inside. The spring piece 212 is connected to the fixed frame 211. When the smart coaster 1 is inserted into the charging slot 23, the spring piece 212 will elastically squeeze and fix the smart coaster 1 to prevent it from shaking or falling off during charging.

[0090] (3) Charging slot 23 layout: The charger 2 is equipped with several sets of charging slots 23, which can be arranged in a linear or rectangular array to meet the charging needs of different users. Users can charge multiple smart coasters 1 at the same time, which improves charging efficiency and makes it convenient for users to alternate between using smart coasters 1 with low power and smart coasters 1 with full power, thus meeting the commercialization of the water cup water volume monitoring system.

[0091] III. Working principle of external controller 3.

[0092] Signal Reception and Display: The external controller 3 and the smart coaster 1 are connected via wireless communication technology. When the smart coaster 1 detects a change in the water level in the cup and sends a signal to the external controller 3, the second wireless receiver of the external controller 3 receives these signals and converts them back into water level information. This information is then presented intuitively on the status touchscreen display of the external controller 3 for the user to view.

[0093] This completes the working process of the water cup volume monitoring system in this preferred embodiment.

[0094] The water cup volume monitoring system of this utility model realizes the intelligent monitoring function of water cup volume through the coordinated work of smart coaster 1, charger 2 and external controller 3, thereby improving the user's convenience.

[0095] In this invention, the drive device 13 and the external controller 3 process the water cup weight signal transmitted by the sensing coaster 12 through preset algorithms and logic. These algorithms and logic may include weight threshold judgment, time window detection, and state switching, used to identify the placement, removal, or weight change of the water cup and trigger corresponding operations. However, these algorithms and logic are quite mature in the field of computer programming and are widely used in various embedded systems and Internet of Things devices. Therefore, the specific implementation details of these algorithms and logic will not be elaborated in the specification of this invention.

[0096] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
